Pearls and Pitfalls

Pearls	Pitfalls
• Suspect subspinal impingement in any case of limited hip flexion and internal rotation • Obtain a false profile radiograph to visualize low AIIS • Use a blunt instrument to palpate bony protrusions extending beyond the capsule before capsular stripping • Avoid tendon damage by placing the external cannula of the burr against to rectus femoris tendon • Prescribe COX-2 inhibitors for 2 wk postoperatively to prevent heterotopic ossification	• Failure to recognize the presence of low AIIS when the bony protuberance is projected anteriorly in anterior posterior radiographs • Overaggressive decompression can cause tendon damage • Wide capsulotomy on AIIS exposure
